Special Combat Aggressive Reactionary Systems, (SCARS) is an American combat fighting system created by Jerry L. Peterson.
Due to its length (taking men out of the field for 30 days), cancellation of some SCARS courses was approved on April 17, 1998 by the Naval Special Warfare Commander, G.M. Moy, Assistant
Chief of Staff for Operations. Navy SEAL CDR Mark D. Divine (Ret.) called SCARS "a very effective offensive fighting system."
